Airflow Diagnostic & Duct Balancing Assessment in South Florida

If some rooms in your home are always warmer or colder than others, the problem usually isn't the size of your air conditioner. It's how the air moves through your ducts. Long or undersized runs, crushed flex, leaky joints, missing returns and dampers set by guesswork all keep air from reaching the rooms that need it. Replacing the AC or adding a smart thermostat rarely fixes that, and closing vents in other rooms often makes it worse.

Swift's Residential Airflow Diagnostic and Duct Balancing Assessment measures what your system is actually doing. We read total external static pressure with a manometer and compare it with your air handler's rated limit. We measure airflow at every supply register with a flow hood or anemometer and compare each room with what its load requires. We run a duct leakage test that pressurizes the duct system to find out how much air escapes before it reaches your rooms. And we take room-by-room temperature readings and scan ceilings, walls and duct runs with a thermal camera.

Then we balance the system: adjusting dampers, correcting register sizes and styles, adding transfer grilles or jumper ducts so closed bedrooms have a return path, and sealing the leaks we can reach. Our target is the same one we design to on new installations, every bedroom within 3°F of the thermostat, consistent with ACCA's Manual RS comfort guidelines.

You get a clear explanation of every reading and of what we changed. If something bigger is needed, such as a new return, duct repairs or a full duct replacement designed with Manual J and Manual D, we'll show you the numbers that support it and give you a price before any further work. The assessment is a paid diagnostic visit, and we quote the fee when you book. Call (561) 685-8408 to schedule.
